java生成word文档

1.pom依赖

    <dependency><groupId>cn.hutool</groupId><artifactId>hutool-all</artifactId><version>5.8.18</version></dependency><dependency><groupId>org.apache.poi</groupId><artifactId>poi-ooxml</artifactId><version>4.1.2</version></dependency>

3.效果

4.说明

说明一：想要把文档中table的表头改成汉字，只需要在实体类上加上注解

@Alias(value = "名称")即可。

说明二：想要采用接口调用的形式，需要将代码中的

writer.flush刷新到HttpServletResponse即可。如下：docXXX方法，改造一下doc()方法即可

    public void listExport(HttpServletResponse response) {Word07Writer writer = docXXX();response.setContentType("application/vnd.openxmlformats-officedocument.wordprocessingml.document;charset=utf-8");Date date = new Date();SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMddHHmmss");String format = sdf.format(date);response.setHeader("Content-Disposition", "attachment;filename=" + format + ".docx");ServletOutputStream out = null;try {out = response.getOutputStream();writer.flush(out);} catch (IOException e) {throw new RuntimeException(e);} finally {writer.close();IoUtil.close(out);}}
